paq is logically equivalent co: *
O - (p - -q)
O (p - -q)
O (-p - -g)
O (-p - q)
O -(-p - q)
p+q is logically equivalent to: *
O (p - q) – (a –→ p)
O (p - q) v (q → p)
O (p- q) a (a - p)
O (pa q) – (q A p)
O (pa q) a (q A p)
The compound propositions p and q are called logic ally equivalent if_
is a tautology.
O p+9
O p-q
O - (p v q)
